IMPROVEMENT IN STEAM WATER-ELEVATORS.

Specification forming part of Letters Patent No. 133,750, dated December l0, 1872; antedated December 4, 1ere.

` To all whom it may concern: "i

Be it known that I, WILLIAM BUnnoN, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Apparatus for Raising and Forcing Water by the Condensation and Pressure of Steam and I do hereby declare that the following is a full, clear, and' exact dcscription thereof, reference being had to the accompanying drawing forming a part of thisspeciication. Y

This invention relates to an apparatus, for raising and forcing water, of that class' in which avacuum is formed in one end and the other of two adjacent chambers, alternately,

4and from which water raised into them by atmospheric pressure is afterward expelled by steam, which is subsequently condensed to form a vacuum for the repetition of the operation. rJhe improvement consists in a novel system of receivers, pipes, and valves whereby water collected in the said receiver during the vdischarges of the chambers is made to effect ranged side by side, but may be in any other suitable relation to each other, and may be of any shape desired. Each communicates,

through a suction-valve, B,with a pipe, G,

and is provided near its bottom withla discharge-openin g, D, the latter being fitted with a valve, which is not shown. 'Ihe said chambers are provided with condensing-pipes E E, which communicate, each, from the lower portion of one chamber to the upper portion of rthe other, and each of which is fitted with a check-valve opening only toward its upper` end. The valve-box V is of horizontal cylinvdrical form, and communicates with the chambers A A through portsa a, and has communicating with it a pipe, F, from a steam-generator. The valves consist of two pistons, Gr Gr, secured to the same stem c, at such distance apart that when either uncovers the port a of -its respective chamberA the other covers the port a of the other chamber. In the valvebox, beyond the valves, are loose pistons I-I, which are caused to abut against the ends of the valve-stem c, and so reverse the valves. I I are upright receivers, one for each cham-- ber A, arranged outside ofthe chambers, and communicating with them close to their bottom. These receivers are furnished, at their communications with their respective chambers, with puppet-valves J J, opening toward the chamber. Connected withthe tops' of these receivers are siphon-like pipes K K, which communicate with the lower portions of the'chambers and pipes L L,wl1ich communicate with the valve-box outside of the piston H. The receivers I I ll through the pipes K K, and these latter are fitted outside of the chambers with cocks f f to provide for regulating the time occupied in filling the receiver so that it may coincide with that occupied in discharging the chamber.

The apparatus is started by lling the chambers A A with water, either Aby pouring it in through openings that are afterward closed, or by shifting the steam-valves and admitting steam to the chambers, and allowing it to condense and form vacuums into which water will be caused to enter through the suction-pipe by atmospheric pressure. When the chambers are full of water the steam-valve is brought by suitable hand-gear to a position to admit steam to one of the chambers, which, for convenience, I will suppose to be the right. The steam thus admitted, acting on the water, eX- pels .it from the chamber through the discharge-pipe D, but at the same time forces some up the pipe K int-o the receiver I, and, after this is filled, up the pipe L into the valvebox V, where, acting on the right piston H, it causes it to abut-against the valve-stein c and move the valves. The slight reduction of pressure which takes place inthe right Water flowing from the conchamber by the shifting of the valves expels the water from that chamber and forces some into its receiver I, and, when this is full, through its pipe L into the valve-box V, Where, acting on the left-hand piston H, it causes the latter to abut against the valve-steine and move the valves to the right, thereby shutting oi' steam from the left chamber and admitting it to the right one. Condensation is then produced in the left chamber by water from its respective receiver I an dpipe E, and a vacuum is formed therein, so that it will be filled through its pipe D by atmospheric pressure, While the right chamber is again discharging. In this way the operation of the apparatus continues to perform itself automatically, each chamber alternately lling anddscharging simultaneously with the discharging and iilll ing of the other.

In case, in the opera-tion of the apparat-us, the discharge of either chamber A, down to the bottom of its respective pipe K, should occur before its respective receiver I should Witnesses:

have been filled with Water, steam will rush from the chamber A through the pipe K, and through the upper part ofthe receiver, and through the pipe L, and thus produce the 0peration of the piston H and valves G G iu the same way as such operation has been described as produced by the Water.

I do not confine myself to the use of the particular kind ot"'valve represented for admitting and shutting ofi' the steam; but

`Vhat I claim as my invention, and desire to secure. by Letters Patent, isi.

1. The combination, with the chambers A -A and the steam valve or valves of the waterreceivers I I, pipes K K and L L, and valves J J, the Whole arranged for operation substantially as herein described, for the purpose set forth. Y

2. The regulating-cocks ff, in combination with the pipes -K K, chambers A A, and receivers I I, substantially as and for the purpose herein described.
